INKlNG-ROLLER.

SPECIFICATION forming part of-Letters Patent No. 345,035; dated July6,1886. Application filed January 15, 1886. Serial No. 188,667. (Nomodel.)

To all whom it may concern:

Be it known that I, MARTIN V. B. ETHRIDGE, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inInking-Rollers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it up pertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of. this specification.

My invention relates to an improvement in inking rollers or pads for usewith printingpresses 01' other printingmachines, particularly suchrollers as are covered with a felting or similar material for holdingthe ink; and the invention consists in a suitably-constructedr0ller-body,which is first covered with felt or similar material forholding the ink, and over which felt is placed a second covering ofcloth, through which the ink in the felt will exude in such a manner asto distribute itself evenly over the type when the roller is broughtinto contact with them for the purpose of inking; and the inventionfurther consists indevices for securing the outer cloth covering uponthe roller, so that no stitches or seams will be exposed to catch intoor be cut by the type or other projecting points, but the periphery ofthe outer envelope shall be smooth and unbroken.

In the annexed drawings, illustrating my invention, Figure l is an endelevation of the roller. Fig. 2 is an end view with the outer plate orhead removed, so as to expose theinner mechanism. Fig. 3 is across-section on the line ac x of Fig. 2, and Fig. 4 is a detail view ofone of the end plates.

Like letters of reference designate like parts in the several views. I

The body G of my improved'roller consists in a cylinder made of anydesired size and of any suitable material. This cylinder is providedwith a central perforation, A, through which passes the shaftforsupporting the roller, and to each end of the body G is preferablysecured a plate, B and B.

The cylindrical body G is covered on its periphery with a layer of felt,G. of greater or less thickness. as desired, (see Fig. 2,) and outsideof the felt is a'second covering of cloth, D, preferably of fiuemeshedcloth.

The manner in which this cloth covering D is secured to the roller is asfollows: At any convenient point in the cylindrical surface of theroller-body a transverse slot, f, is cut, extending into the roller ashort distance until it meets a circular hole or aperture, F, whichextends through the cylinder-body from end to end and parallel with theslot f. Within the circular opening F is a short rod orshaft, d.journaled at either end in the plates B and B, in such a manner that itcan be rotated.

To one'side of the aperture F is a second aperture, I, preferablysmaller than the aperture F, and, like said hole, extending from end toend through the body G. The two perforations F and I communicate bymeans of a slot, 9. Now, the cloth covering D, being cut to the properwidth and to a length considerably in excess of the length of theperiphery of the roller, is placed around the roller and the two ends aand-b of said covering folded within theslot f, as shown in Fig. 2.Before inserting these ends, however, into the roller-body the end I) iswrapped once or twice about aremovable pin or post, a, and secured to ittightly, and the end a is wrapped about and secured to the shaft (1. Theparts are then placed in the relative position shown in Fig.2, the endI) passing through the slot 9, as well as through the slot f, and thepin 0 being placed tightly within the perfo- -ration I. The end plate,which must be removed in order to place the parts in theirproperposition, is next secured in place, which will give the shaft d itssecond bearing, one bearing being found in the other plate already inplace. Obviously, now, if the shaft 11 be rorated, the enda of the clothwill be rolled upon it andthe covering be drawn tightly around theroller. of the shaft, one end thereof is provided with a screw-head, 6,located outside of the plate B, (see Fig. 1,) also with a ratchet-wheel,D, which is held in any desired position by a 'pawl, E, which in turn isheld against the 100 In order to facilitate the rotation 5 ratchet bymeans of a spring, H. Any ordinary screw driver can be applied to thescrew-head for operating the shaft, and thereby tightening the clothcovering D, and the pawl and ratchet serve to keep it tight.

In using my improved roller, the outside is covered or saturated withink, so that it will squeeze or soak through the outer covering into thefelt, which acts as a reservoir to receive the ink, and when in actualoperation the roller-surface comes into contact with the type-faces theink will squeeze through the interstices in the fine-meshed cloth anddistribute itself evenly over the outside of the same. This isadvantageous, in that the fuzz of the felt will not come into directcontact with the type, to leave its filaments thereon, and thus clog andblur the printing. The ink will be better distributed, agiven amountwill last a longer time, for the whole supply will not be brought intocontact with the type each time the roller touches them; the printingwill be neater, and both the working and the results will be of a higherorder than heretofore. Further, the manner of attaching the covering, sothat no stitches or seams shall be exposed, prevents the ripping ortearing of the cloth, which would otherwise occur when the threadscaught the type, and prevents the cutting or tearing of the threads bythe type.

It will be noted that I do not confine myself to the mechanism shown anddescribed for tightening the outer cloth covering. There are many waysin which the tightening may be effected without departing from thespirit of my invention, which includes, broadly, the covering of acylindrical inking pad or roller with cloth in such a manner that nostitches or seams shall be exposed, to catch or be cut or worn by thetype or other projecting points.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent. is

1. The combination,with a roller-bodyhaving a felt surface, of an outerenvelope of finemeshed material, so secured upon the said roller as notto expose any stitches or seams for entangling with or being cut or wornby projecting points on the type, substantially as shown and described.

2. The combination, with a cylindrical roller-body, of an envelope offelt for holding the ink, and an envelope of fine-meshed materialsurrounding the felt, and through which the ink comes into contact withthe type, substantially as shown and described.

3. The combination,with a roller-body having a felt covering, of a clothenvelope whose ends pass into the substance of the roller-body and aresecured tightly, substantially as shown and described.

4. The combination of the roller-body having central perforation, A,transverse slot f, and perforations F and I, connected by slot g, theend plates, B B, the felt covering 0, and the cloth covering D,whoseopposite ends pass through the slotfinto the holes F and I, one end, asb, being made fast within the hole I, and the other end, as a, beingsecured toa shaft, (1, journaled in the end plates and adapted to berotated so as to tighten thecloth covering, substantially as shown anddescribed.

5. The combination. with the/roller-body G and the felt covering 0, of acloth covering, D, and mechanism within the body for tightening saidcovering about the roller, consisting of a shaft, d.' journaled inbearings, and provided with screw-head, wherebyit can be rotated, andwith ratchet and pawl, whereby it can be held at any point, one end ofsaid covering D being secured to the shaft d,while the other is madefast within the roller, substantially as shown and described.

6. The combination of a roller-body, G, a felt covering, 0, the clothcovering D, whose ends enter the roller-body through a slot, f, onebeing made fast and the other being wound upon a shaft adapted to berotated, and held at any point in the rotation by suitable means, as apawl and ratchet, substantially as shown and described.

7. A roller-body having a porous or spongy surface, in combination witha surrounding seamless envelope of thin finely-meshed fabric,substantially as and for the purposes set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
